Abstract:
A PWM control on the active filter for a single phase controlled rectifier is proposed in this paper. This is done
as a comparative study, using two different converters at one pulse control and PWM control (4 pulses) of the active
filter. Both converters are given the same R and RL loads to obtain a comparison of power factor (PF) and Total
Harmonic Distortion (THD). Simulation for this technique has been performed by using the PSPICE simulation
program. The performance of the two rectifiers has been evaluated on the basis of an input current waveform, THD, and
PF. The simulation results showed that the addition of 4 pulses with PWM control on the active filter can reduce
harmonics and it can improve the PF on the rectifier.
